Four colonial soldiers loot an Indian temple, but one is left behind. Terrified of being caught by their fierce sergeant, they kidnap a gullible Irish porter to replace him. Determined not to get caught, the soldiers break down the porter Galy Gay through a series of outrageous trials, including witnessing his own ‘supposed’ execution and funeral. Singing and brainwashing ensue in this rollicking cabaret-style exploration of identity and the dehumanizing nature of war, where one man is transformed into a One-Man Army.
